Abstract

The object of this invention refers to a new foldable container in a parallelepiped shape with all sides being rigid and flat, fitted with an articulation and guiding system that permits folding of the sides over the base in an opposing manner through the turning of one end and sliding of the other towards the inside of the container, only through vertical movement of the roof. It permits the use of conventional doors half the width of the container. The improvements account for an innovative system that permits the folding/unfolding movement without substantially modifying certain characteristics of conventional ISO containers. The design caters for container versions where the doors are higher than the width of the container.
